MIXING DEVICE 'new and usefu Improvements in Mixing Devices, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to a mixing device that may be utilized forcarbui'eting, atomizin and vaporizing purposes.

T e primaryy object of inv invention is to provide positive and reliablemeans, in a manner as hereinafter set forth for causing an admiiiture ofliquid and fluids by centrifugal force, comminglin 4of-liquid and fluidmolecules and thero' uction of an admixture that is highly etlicient forthe purposes for which it using the. centrifugal force asainixing'ilieium or agent, such liquid', as

of parts to be hereinafter specifically described and then claimed'.

Reference' will now be had to the drawings, wherein- Figure 1 is a frontelevation of the mixing device, partly broken away and partly insection; i

Fig. 2 is a detail view of a portion of a rotary mixer;

Fig. 3 is a vertical longitudinal sectional view ofthe device, and

Fig. 4 is a detail view of one of the elements of the humidifier,

In describing my invention by aid of the views above referred to, Idesire to point ou! that the same are intended as merely illus trativeof an example by which my inven tion may be put into ractice, and I donot care to' confinqmyselli to the precise construction and arrangementof parts shown. The following description is therefore to bebroadlyconstrued as including such substitute constructions andarrangement of parts which' `are the obvious 'equivalent of those to behereinafter referred to. f

In the drawings, 1 denotes a 'humidifier that is somewhat invertedU-shaped and 'has lower open ends in communication with a tankorrese-rvoir 2. The shape of the humidifier structure 1 provides acentral coin- `partment 3 andl the front of the humidifier structure isclosed 4by the rear wall 4 of the 5 is circular in' elevation and has adetachable front wall 6 lprovided with -a central bearing 7. l

The greater part of the rear of the humidifier structure 1 is municationwith a cylindrical fan casing 8.

Adjacent this fan casing isa power translmiion casin 9 affording abearing in open and 'i'ncom-l alinement wit the bearing 7- of thedetach-1 able front-wall 6.

Journaled in the bearing of the casing 9 aud the bearing 7 of the'detachable front wall 6 `is atubular shaft- 10 and mounted on this"shaft within lthe fan casi 8is 'the hub 11 of afan 12; Abuttin'g theub-zllof the fan 12 is the longV hub 13 ofa rota mx ing device withinthe mixing chamcr 5, said device havin radial blades 14 that are curvedfrom the inner ends' thereofto the 4.

outer ende and are (lished or convexe-ronave in cross section. The upperondal ot the blades 14 are in proximity to thc inner ar|- nular wall ofthe mixing rluimher .-'i and a ventral opening l5 in the wall 4lprovidesclearance tor the long hub lll ol' tlul mixing device and al the Ae'anuItime provides an air inlet opening into thtl mixing i-I'iaml'ier. llulnir inlet opening l5 riumnunicafes with the ventral ronumrtment -l ofIthe humidifier l and the passage ot air through said opening iscontrolled by andiak shaped valvular member itl. carried by the end ot asfide sleeve 1T on thel long hub 13 ol the mixing (levier. The sleeve 17has apertured ears I8 and pivotally connected thereto is a lever 1l)extending through an opening 2U provided therefor iu a U-shapedpartition 2l within the renti-al romlmrlment. il. 'l`hc lever lil ispivnl'ally held adjarrnt the -oi'iening 2f). as at llnnd the lower endthereofi# piiotally conm-rind to a rod 2&3 extending through a g-lgmland \'t,lifliiig linx Z-l i'arried by fluI tank or rrrioir L'. Byl'eeiprm'aling the rod 23. the Valeoief member lll may be moved to .'nclfrom the opening l5 and thus roiitrt-l the @mount ofl air entering Ihrmixing rhanrber.

'l`lnend of" the tubular shaft. 10 journaled in the bearing 7 is closedby a plug 24 and the inner end of Said plug has a tatit'mary necdievalve while the outer end of Said |.ilug is inclosed by a ca'p 26connected to the bearing 7 or the detachable front wall G. h'lovalile toand from the stationary needle valve is a. recip1 'o ahle tubular valvemember 2i" that protrutiles from that end of the tubular shaft Journaledin the power transmisriion rasinil' ffl. 'lhe easing E) has a l. racketbearinf- 528 as a fulcrum for a. lever 29 aiicffeaid lever has the upperend thereor` op- Irmtirely ronnerted to the tubular valve member JT soas: to reciprocate the Same. A md 30 ma y be m'mnected to the ,lower endof lim lever to facilitate operating the same from a remote point.

l 1-onneeted to the tubular valve member 27 'is a hose or flexibleconnection 31. in cornmunieation with a Supply tank 32 adapted to.ontain a fuel that may be vaporized, as gasolene or kerosene. Theliquid may f'low by gravity into the tubular valve member 27 and fordistributing the liquid in thel mixing chamber the tubular shaft. 10,adjacent ila'- needle valve 25, has radially disposed di.' f=.'h: irgemembers 33 and as best shown in Fig. 3, the outer ends of aid dischargememhere are tunnel shaped or flared. The memhere 35i extend through someof the blades 14 and are adapted to discharge gasolene toward the innerwalls of the mixing chamber 5.

Any suitable power transmission may be located withln the casing l) torotate the tubular shaft 10, and as shown there is a ber, a fan on gearwheel 34 which when revolved, rolatca the tubular srluilt 1f), andplaces the fan l2 in opiiratioin also the rotary mixing device. Hinreflul numbcl's 33 arc carried by the tubular shaft vlt), the gasoleneadmitted to lsaid member will br forciblyl discharged by centrifugall'orre and in thinmanner vaporized on entering the mixing rhambrr.

ln the humidifier l there arc a series of` bafilc plates or mcmbera1supported in staggered relation transversely of the humidifier by theside and. central walls of said humidifier, as shown in lSection in Fig.l. The baille members,I provide a sinuous` tortnous, cirenitoua or stagered path for air from the fan easing 8. a so for a liquid, as water,that. is supplied to the humidifier l by a connection 35. The clemente`arranged within the humidifier 1 are designated Bti and water dripslupon the uppermost elcments to gradually flow over the `aame into thetank or reservoir 2. Air passing between the elements will be ladenwilli moisturiand the moisture will be drawn in'lu the mixing chamber.

ly regulating the supply ol water lo the humidifier 1. theamountofmoiHture rarried into the n'iixing chamber may be varied. :sothat the Final mixture will haveI a degree of moisture which isdesirable, particularly in connection with an explosive mixture, toprevent the accumulation of carbon and other deposits in and about anengine cylinder.

The mixi'ng'-oliainber 5 has a peripheral channel v37 that graduallyincreases in cross sectional area to an outlet (':onneeti'on 38, andwhen the mixing device is used as ay carbureter in connection with aninternal eembustion engine, the outlet. connection 38 is connected tothe intake manifold or intake chamber of the engine.

ln operation, the valvular members 1G and 27 control the admission otliquid and fluid, as gasolene and air, to the mixing chamber 5, and withthevmixing device rotating in said chamber, it is apparent that. themoisture ,laden air is forcibly drawn into the ehainber. .Since themembers33 are carried by the mixing device, tilie'gasolene is dischargedby centrifugal force and isA vaporized to that extent that particlesthereof eau intimately commingle with the air in the mixing rlnm'iber. Athorough mixture is assured by the rotary mixing device and this devicewill tend to compress the mixture in the outlet connection 38 and amanifold or chamber to-whih it may be connected.
